The GefenPRO GEF-HDFST-444-4ELR is a 4x4 HDMI Matrix Router. The HDMI router uses bi-directional IR to route to 4 HDMI sources, and supports 3DTV pass-through with eight digital audio channel formats such as Dolby TrueHD and DTS-HD Master Audio. Bi-Directional IR allows the source to be controlled from the viewing location, when used with optional GEF-HDFST-4IRKIT, sold seperately. 3D content can be displayed when connecting a 3DTV and 3D source. The unit supports resolutions up to 1080p Full HD with Deep Color and multi-channel digital audio to all four HDTV displays. Each source is accessible at all times from any display location while Gefen's fast switcing technology (FST) accelerates the HDCP authentication process. Receivers are included and used to extend HDMI to all four locations using ELR and POL technologies. ELR is based on HDBaseT and allows the extension of HDMI using a single CAT5e cable. POL eliminates the need to externally power the Receiver units. The IR All Out port on the matrix broadcasts IR commands from any of the viewing locations to all sources. The IR All In port on the matrix broadcasts IR commands from an automation control device by the matrix to all remote displays. The matrix can be controlled by using the included IR Remote, RS-232, IP control (Telnet or Web server interface), or by using the front-panel push buttons.

How It Works:

Using HDMI cables, connect up to four Hi-Def sources to the four HDMI inputs on the matrix. Connect up to four HDTV displays receivers included with this router, using HDMI cables. Use a single CAT5e cable, up to 330 feet (100 meters), to connect each of the receiver units to the matrix.

  • To control each Hi-Def source from the display location: connect an IR Extender to the IR Ext jack on each Receiver unit. Connect an IR Emitter to the corresponding IR Out for each source input on the matrix and place the IR emitter over the IR sensor of the Hi-Def source. Point the IR remote of that source towards the IR Extender at the display location to control the source.
  • To control the display placed near the Receiver unit: connect the IR Emitter output from an automation device (such as the Gefen PACS or MINI-PACS) to the corresponding IR Input on the matrix. Connect an IR emitter to the IR Out on each Receiver unit, and attach the IR emitter over the IR sensor of the display.

What is Gefen FST Fast Switching Technology (FST)? FST is a software implemented by Gefenfor HDMI products. FST was created to improve the lengthy HDMI authentication process, based on the HDMI and HDCP specifications. FST allows for connecting/disconnecting or turning any of the HDTV displays on or off without affecting other displays within the audio/video distribution system.


  • Shielded (STP) CAT5e or CAT6a is recommended. Unshielded (UTP)CAT5e or CAT6a may be acceptable depending on cable quality but is not the top choice.
  • POL (Power Over Line) technology from Gefen uses the Ethernet channel to send power to the Receiver unit.
